INTRODUCTION
1. Before installing the electric heater, read these instructions
carefully. Failure to follow these instructions could damage the
product or cause a hazardous condition.
2. Check the ratings on the heater label to assure the product is
suitable for your application.
To avoid electric shock and equipment damage,
disconnect any power supplies to the enclosure before
installing the electric heater. Do not energize any
circuits before all internal and external electrical and
mechanical clearances are checked to assure that all
assembled equipment functions safely and properly.
WARNING
GENERAL SAFETY INFORMATION
1. Protect the lead wires from coming in contact with sharp objects,
hot surfaces, and/or chemicals.
2. If continuous operation of the heater is essential to the safe
functioning of any other equipment, adequate warning devices
must be installed to assure safe operation at all times.
Do not use these electric heaters in dusty, dirty, corrosive, or
hazardous locations.
Reduce the thermostat from factory setting to a recommended setting not to
exceed 75 F for most applications.
CAUTION: SURFACE MAY BE HOT.
ATTENTION: LA SURFACE PEUT ÊTRE CHAUDE.
Adequate protection must be taken to protect people from potential burns and
to protect other components from this heat. Always allow the heater to cool
before touching it.
Thermal sensitive devices or materials may need to be located further from
the heater than the minimum recommended distance.
Heaters must not be installed on wood or other combustible surfaces.
NOTE: INSTALLATION IS TO BE MADE ONLY IN A TOTALLY
ENCLOSED METAL ENCLOSURE.
NOTE: L’INSTALLATION DOIT ÊTRE EFFECTUÉE SEULEMENT DANS UN
BOîTIER MÉTALLIQUE QUI EST TOTALEMENT FERMÉ.

LOCATION AND MOUNTING
1. Hoffman electric heaters should be centered as low as possible in
the enclosure for optimum heat distribution.
2. It is recommended that the heater be installed on a non-
combustible metal panel for optimum performance. It may,
however, be mounted on any metal surface.
WARNING: Heaters must not be installed on wood or other
combustible surfaces.
3. The heater should be mounted in a vertical position with the
terminal block at the bottom and the air outlet openings at the top
as shown.
4. The recommended clearances shown by the shadowed area
indicates the space that should be kept free of components for safe
operation of the heater.
WARNING: Heat sensitive components must not be placed above the
heater discharge area.
5. Four 10−32 UNF, self−tapping screws are included for installation.

WIRING
Reference Wiring Illustration on page 6
1. All wiring must comply with applicable local codes and ordinances.
2. Connect the heater lead wires to the proper A.C. power source.
Power source for 800 and 1300 watt heaters should be continuous.
3. The heater must be properly grounded.
NOTE: Exposed wires should not come in contact with the
heater housing.
SETTING THE THERMOSTAT
1. The heater is controlled by an adjustable thermostat. Set the
thermostat to the desired temperature. It is recommended not to
exceed 75 F for most applications.
MAINTENANCE
1. Always disconnect power supply before inspecting or working on
the heater.
2. Generally the unit requires no maintenance since the fan bearings
are permanently lubricated and sealed.
